General Description

The ELH0021 is a general purpose operational amplifier capa-

ble of delivering large output currents not usually associated

with conventional IC op amps; the ELH0021 will provide out-

put currents in excess of 1A at voltage levels of g12V. In addi-

tion, both the inputs and outputs are protected against over-

load. The device is compensated with a single external capacitor

and are free of any unusual oscillation or latch-up problems.

The excellent input characteristics and high output capability

of the ELH0021 make it an ideal choice for power applications

such as DC servos, capstan drivers, deflection yoke drivers, and

programmable power supplies.

Other applications include torque drivers for inertial guidance

systems, diddle yoke drivers for alphanumeric CRT displays,

cable drivers, and programmable power supplies for automatic

test equipment.

The ELH0021 is supplied in an 8-pin TO-3 package rated at

20W with suitable heatsink. The ELH0021 is guaranteed over

the temperature range of b55§Ctoa

125§C.

Elantec facilities comply with MIL-I-45208A and other applica-

ble quality specifications. Elantec’s Military devices are 100%

fabricated and assembled in our rigidly controlled, ultra-clean

facilities in Milpitas, California. For additional information on

Note 1: Rating applies for supply voltages above g15V. For supplies less than g15V, rating is equal to supply voltage.

Note 2: Rating applies for ELH0021K with RSC e0X.

Note 3: Rating applies as long as package power rating is not exceeded.

Note 4: Specifications apply for g5V sVSsg18V.

Note 5: The ELH0021, like all Class B amplifiers, has a ‘‘dead band’’ when VOUT is near 0V. Typical values for the ‘‘dead band’’ are

in the 50 mVto200mV range. Open-loop gain is measured at VOUT from g0.5 VDC TO g10.0 VDC which is out of the range

of the ‘‘dead band’’.
